Re: Probe EGT in quiescence?

Certainly it does contain those basic combinations you've mentioned, they are essential to any bigger tablebases. But there isn't any download page, are you referring to the list pages? I knew you have full basic EGTs since I have visited your page of EGTs, found some and check their sizes already ...

Re: How far away are we from deep learning Stockfish, Komodo

Would it be for example possible to take Stockfishs code and change only the evaluation function into an deep learning evaluation function? And also use cpu + gpu for different tasks? Maybe a code mix of Giraffe and Deep Pink and some improvements would be a better deep learning engine? Why are you...

If so, loading the list pages would take a while (~3mb in html), perhaps you can try refreshing and wait a bit. Al...

Re: Probe EGT in quiescence?

Wow, are you the author of cyclone? The engine is so good! Yes agreed, look like so far EGTs are not a mystery for chess engines. However I want to know clearly their limits, especially in new model hardware where memory become so huge. Do you load your EGT into memory and probe it in quiescence? N...

Re: Probe EGT in quiescence?

Probing DTx tablebases during search is not really necessary, you can simply probe WDL tablebases and give it a pesudo-mate score, then probe DTx tablebases when you actually reached that position. I'm hosting a comprehensive set of DTC/DTM tablebases online, with a public query interface. Also acc...

Re: Probe EGT in quiescence?

Longest DTC I have so far: http://i.imgur.com/mCOHrDa.png I think we don't need to worry too much about DTx sizes, they will eventually grow too large when you add more and more pieces. My current set of corresponding WDL tablebases already reached 2TB after compression, so I'm more interested in: -...

Re: How far away are we from deep learning Stockfish, Komodo

My idea, if we can use NN to filter out X% from all possible moves with Y% overall accuracy while slowing down the engine by no more than Z% and manage to achieve (1 - X) * Y > Z, that can be an improvement. I just wonder isn't that what we've always been working on, null move, probcut, history heur...

Re: How far away are we from deep learning Stockfish, Komodo

Let me just re-phrase my one-line sentence into many. Why NN is good for Go, as described by HGM, is because currently there is no better modeling/scoring methods than heuristics from machine learning, plus the nature of Go: search space gradually shrinks and MCTS friendly. When it comes to the ques...

Re: How far away are we from deep learning Stockfish, Komodo

After some garage experiments, I think NN-based eval for chess is pretty much a joke even compared to current PST+MAT eval alone.

At most, it might be good for move pruning and sorting, prove me wrong.
